ok looking for a little info the truck is a 85' f150,2wd, with a 300, carbed, duraspark II ignited, 4spd (1,2,3,OD) Manual, 200K Km's, im looking to swap in a 88 or 89(forget the year) 302 from a buddys crown vic. My question's are:

what will i have to change on the engine?
im figuring the intake and dizzy (i have a 2bbl intake off a 85 302 will it work?),

im going to need a fuel pump right since the efi pump was in the tank and the truck is on the 300 ya? would a inline like a holly "Blue" work? if so what should it be regulated to? or would that depend on the carb i used?

i have been told that the trans will bolt right up ya?

are the mounts the same or will they have to be move/fabed?

will a MDS 6AL and a 8579(small diamiter pro-billit) MDS distro work on there own or will it need to have some sort of the ford ignition system too? guess im askin if its "stand alone"


i think i have missed a few but this will get me started
Thanks all

 

 

wow thanks for the quick info

im lost on your description of the fuel pump system?
ok
car has in tank pump (88/89 efi)
truck has engine mounted mech pump(85 carbed)

so on the truck i should be able to just put a inline pump (and regulator if needed)like the holly and be good to go?

fuel PSI at the carb? depends on the carb or is it standardized?

lol ya won't forget the coil

thanks
Joe

 

My mistake I was thinking two different things. Your truck is carbed now and the donor motor is efi. Your wanting to switch to a 2bbl carb setup, on the efi motor and drop it in your truck.

www.summitracing.com www.jegs.com Carter has a 5psi electric pump, (no regulator required) $57.25 U.S.

www.jcw.com Jcwhitney has a few (no regulator required) for $40 +/- U.S.


Or your right a holley and adjustable fuel pressure regulator would work. I thought you had a efi 300 when I wrote my reply, sorry, you did write "...with a 300, carbed,..". Sorry for the confusion

 

the 85 carb is probably a feedback carb and if it not hooked up to the computer it won't work right

 

its a canadian truck with DS II so the carb is wire free (also factory Cat less as well(no smog stuff) )

what im after is to lose all the "computer" crap in the swap i dont mind the MDS stuff due to the advantages it has.

went looking last night and the 2v intake was MIA so i guess im buying one so its going to be a 4v DP
like the edelbrock (EDL-2121) (non-EGR, idle-5500rpm, cast aluminum) and a edelbrock 500cfm carb to top it off (EDL-1404)

my main worie about the fuel pump is reliability
hope the carter pumps are better then the carter single barrel carb thats on the 300 lol its always messing up it seems

thanks again all
Joe
Merry Christmas!

 

try max 7 psi. for fuel pressure as little as 4 psi may work fine, you'll need the exhaust crossover and the brackets from a truck 302 for your accessories, the water pump on a truck is reverse rotation and if your donor motor came from a car you will either need a new timing cover off a truck engine to run a rev. rotation water pump because a car water pump will bolt up but the output ports don't line up . If you have a car engine and don't want the hassle of changing the pump and timing cover then you have to run the two belts as a car and get the appropriate brackets for a car. you need a new radiator as the six has the input and out flow reversed from a v8, I'm in the process of doing the same ting right now and it's really just a bolt-in with a few glitches.

 

thanks for the info daerhldgs2

His '85 truck will not be reverse rotation, it does not have a serpentine belt setup on the 300-6. The 88-89 302 will have a serpentine belt setup unless he does not have the complete setup including brackets, pulleys, alt, A/C, PS, and bolts to keep it all together. You can make the 300-6 radiator work, just take it to a radiator shop and have them reverse the inlet side and the outlet side, easy, $20 bucks max.

Back to the water pump, If you do not have the serp setup for the 302, you will have to collect the following:

Pulleys: single groove PS, double groove water pump, double groove crank, single groove ALT, and single groove AC.

Brackets: Find a setup for a 85 1/2 or older Ford car( or truck) with a 302 or 289 with the alternator on the passengers side, and the PS on the lower drivers side.

Timing cover: You will need a timing cover from a 85 or older CARBED 302. These are standard rotation waterpump compatible. The EFI covers are not. This will solve the fuel pump issue, as the carbed cover has the cutout for the mechanical fuel pump. (FYI, there is one year and one car that had a serp belt, reverse rotation WP, and a mechanical FP. An 85' Mustang GT w/5spd manual trans. A hard find, but was a ford part for one year. Automatic 5.0L 'stangs were full EFI. Manuals were still Carbed.) Summit makes a cover that accepts standard or reverse Water pumps, and has the FP cutout. $110 last I looked.

Water pump: You will need a standard rotation WP for this setup.

If you go with the mechanical FP setup, you will need to find and buy a fuel pump eccentric to fit the 302. EFI's did not come with them.


Hope this helps.
